You can use the cosine law with the formula:
a^2 = b^2 + c^2 - 2*b*c*cosA
With a = 5, b = 5, c = 7,
7^2 = 5^2 + 5^2 - 2*5*7*cosA
49 = 25 + 25 - 70*cosA
70*cosA = 25 + 25 - 49
70*cosA = 1
cosA = 1/70
A = arccos (1/70) = 89.18 deg = 89 deg
Andy is not correct because when adding the 2 fractions, he needs to create fractional parts with the same denominator. NOTHING can be added unless the units are the same. The denominator of a fraction are the units. He needed to make 3/5 = 12/20 and 1/4 = 5/20. Adding these together would be 17/20, making 3/20 of them NOT action or comedy. 17/20 + 3/20 = 20/20 or the total.
2*2*2*2*3, it's all the prime numbers that make 48 when multiplied together
Answer:
Option 1
Step-by-step explanation:
First we need to analyse the question to figure out what we need to do. The question is saying that a line is parallel to the y-axis. We know that the y-axis goes up and down, meaning that our line should be pointing up and down crossing the point (2,-7). In order to find where the line is placed, we would have to look at the x-axis to figure out where it is. Using the info provided we could see that the line has to pass (2,-7), and the x for that point is 2. Using all the info we have concluded we know that the equation of the line is x=2.
